Abstract
BACKGROUND: Medical decision-making is a complex multi-stage process. Chinese cancer patients' preference for participation in decision-making stages, family involvement and influencing factors remain unclear. METHODS: A total of 1,422 cancer patients from four tertiary hospitals in China were included in the cross-sectional survey. Patient Expectation for Participation in Medical Decision-making Scale was used to measure patients' information, deliberation and decisional control preferences. The patient-family Control Preferences Scale was used to measure expected and actual levels of family involvement. Generalized estimation equation was performed to explore factors associated with patients' preferences. RESULTS: 93.0% of patients had a high preference for information exchange, 95.8% for treatment deliberation, and 61.7% for decisional control. Equal participation was most common in family involvement in decision-making, followed by family-led and patient-led. 15.5% of patients reported a discrepancy between expected and actual family involvement. Age, education, marital status, number of adult children, occupation, family income, regular residence, health insurance and time since diagnosis were related to patient preference. Compared to patients with other cancer sites, those with breast [odds ratio (OR) 2.02, 95%CI: 1.47-2.77] and thyroid cancer [OR 2.37, 95%CI: 1.82-3.10] had higher information preference, those with breast [OR 2.98, 95%CI: 2.73-3.26] and esophagus cancer [OR 2.86, 95%CI: 1.13-7.22] had higher deliberation preference, and thyroid cancer patients [OR 1.50, 95%CI: 1.07-2.10] had higher decisional control preference. Patients who expected or experienced equal participation had higher preference at all stages of decision-making than those with family-led involvement. Patients with inconsistent expected and actual family involvement had lower preferences for the deliberation [OR 0.53, 95%CI: 0.36-0.77] and decisional control stages [OR 0.67, 95%CI: 0.56-0.79]. CONCLUSIONS: Chinese cancer patients generally have high preference for information exchange and treatment deliberation, but varied preferences for decision control, influenced by patients' sociodemographic factors, cancer types, time since diagnosis and family involvement. The findings underscore the importance of tailoring medical decision-making processes to individual patient preferences and ensuring family involvement aligns with patient expectations to enhance patient-centered care in China.
